Altius Transaction SDK

This crate provides utilities for signing and encoding Altius USD multi-token transactions. It can be used by:

• explorer-api for faucet functionality
• Any client that needs to send transactions to Altius

Security Note

This SDK does NOT contain any private keys or addresses. All chain-specific configuration (fee token address, faucet keys, etc.) must be provided by the application layer through environment variables or configuration files.

Example

use altius_tx_sdk::{TxBuilder, Signer, BASE_FEE_ATTO, Address};

// Create a signer
let signer = Signer::from_private_key("0x...")?;

// Build an ERC20 transfer transaction
let tx = TxBuilder::new()
    .chain_id(1337)
    .nonce(0)
    .erc20_transfer(token, recipient, amount)
    .fee_token(fee_token)
    .max_fee_per_gas_usd(BASE_FEE_ATTO * 2)
    .build();

// Sign and encode
let raw_tx = signer.sign_and_encode(tx).await?;
